Title: Ultrasound defectoscope
Inventor: KALININ VLADIMIR A
IPC: G01N29/04
Filed: 1990-03-05
Abstract: The flaw detector is used for controlling rails and welded stitches, and has an  enhanced accuracy. It consists of a multi-vibrator, with a time regulation for sensitivity, the inlet of which is connected to the outlet of a multi-vibrator for stroking impulses, a pressure formator, with time regulation of sensitivity, and a commutator (the outlet of which is connected to the outlet of the attenuator for time regulation of sensitivity), and a multi-vibrator with a zone for automatically regulating amplification. The multi-vibrator's inlet is switched to the outlet of the multi-vibrator for stroking impulses, and its outlet - to an inlet of a scheme for stroking and a second "AND" scheme. There is also an indicator for contact presence, the inlet of which is tuned to the outlet of the amplifier with automatic amplification regulation.

Title: Bubble level meter and related method
Inventor: BOUCHARD CLAUDE
IPC: G01F23/14
Filed: 2002-02-26
Abstract: The invention concerns bubble level meter having a pneumatic tube (2) connected to a gas generator (12) and to a pressure sensor (14). A deflecting valve (16) is interposed along the pneumatic tube, for deflecting the air outlet at a predetermined height from the usual lower outlet (8) of the tube. A control circuit (20) controls the deflecting valve and the gas generator based on predetermined set values, processes the pressure measurements obtained from the pressure sensor, checks the calibration of the sensor on the basis of the measurements and the difference in height between the tube outlets, and generates level data based on the processed pressure measurements and a calibrating coefficient. Another valve (28) interposed between the sensor (14) and the tube (2) and monitored by the circuit control (20), enables to take into account the possible drift of the sensor.

Abstract: In a common bus control method, transmission and reception buses are connected to a unit having a unit number 1.  A synchronization frame head  signal for time-division slots of common buses is sequentially supplied to the units in the order of the unit numbers 1 to n through delay circuits.  Phase correcting circuits are respectively connected to the  transmission and reception buses of each unit so as to perform phase correction of data on the buses and latch signals for latching the data.          The delay circuit arranged in each unit sets transmission delay data having an inherent delay difference on the basis of the synchronization frame head signal. An output from the delay circuit of each unit is used as the latch signal.

Abstract: A sheet metal made from a ferritic stainless steel alloy which has an improved corrosion resistivity and is suitable for use in manufacturing exterior building material, in particular, roofing material, by means of forming process such as roll-forming, without formation of pocket wave.  The steel alloy comprises 10-32 wt% of Cr and 0.005-0.1 wt%, in total, of C and N, the balance being Fe and unavoidable impurities.  The sheet metal has been processed to present a mechanical property that, when tested in a tensile test conducted for a test piece sampled in the widthwise direction of cold-rolling and measured at the elastic limit reached in the test, a strain ratio is equal to or greater than 2.5.    The method of making the sheet metal comprises the steps of: cold rolling a steel slab into a sheet metal, subjecting the thus obtained sheet metal to final annealing, subjecting the sheet metal to skin-pass rolling, and, subjecting the resulting sheet metal to aging process at a temperature of 200-550°C for a time period of more than 5 seconds and less than 48 hours.

Abstract: ABSTRACT OF THE DISCLOSURE:    In this ceramic engine, the cylinder liners are formed out of a ceramic material, and bearings consisting of a ceramic material are installed in the rotary sliding portions of a crankshaft and larger- and smaller-diameter parts of connecting rods, suction ports being formed in the cylinder liner lower portions so as to be spaced in the circumferential direction thereof, these suction ports and crank chambers communicating via first suction passages, fuel alcohol supply means being provided in second suction passages through which suction air is introduced into the crank chambers.     Accordingly, lubricating films of ungasified components of the fuel alcohol are formed on the sliding surfaces of the pistons and cylinder liners and those of the above-mentioned rotary sliding portions, and these sliding surfaces and rotary sliding portions are kept in an excellently lubricated condition owing to such lubricating films.  Moreover, the alcohol collected in the crank chambers and the alcohol constituting the lubricating films on the above-mentioned sliding surfaces and rotary sliding portions are burnt in order, and suction air is supplied through a low-temperature portion of the engine.  Therefore, the suction efficiency does not decrease, and the efficiency of the engine can be improved.

Title: Suction cup clamp hanger
Inventor: THERIAULT YVES
IPC: A47G1/17
Filed: 1990-07-09
Abstract: ABSTRACT             The new Suction Cup Clamp Hanger uses a suction cup and the attraction of two magnets to generate a friction force, to hang up posters and placards to windows or other high gloss surfaces.  The device does  not  deteriorate  the  sign  material  or  the mounting surface.  The device keeps the sign at a certain distance  from  the  window  to  allow  air circulation between the placard and the mounting surface.  The new clamp can retain placards made of paper, cardboard, plastic, metal, glass, wood and composites.   The clamp is opened by peeling the flexible magnetic strips apart.  The holding force of the clamp depends on the thickness of the placard and the dimensions of the magnets.  Several clamp hangers can be used to hang up heavier signs.
